Abstract：
The principle of beam position monitoring of button was introduced briefly. It was compared with beam bugs in principle. Based on the result in simulation experiment, a new structure of button was design, and some mistakes in the primary design was correctted. In the realy beam experiment of “Dragon Ⅰ”, the beam waveform and position were monitored. Compared the position curve between button and beam bugs, that indicated the data that got form button is credible. In the experiment, the button have an accuracy of 0.5mm, which is adequate for beam position measurement of “Dragon Ⅰ”.
